3. The battery of claim 2 , wherein said Radio Frequency Identification element comprises at least one antenna ( 20 ).
4. The battery of claim 3 , wherein said Radio Frequency Identification element comprises a plurality of antennas ( 20 ) in order to communicate over different frequencies and/or different communication protocols.
5. The battery of claim 1 , wherein said Radio Frequency Identification element is powered by said battery cells.
6. The battery of claim 1 , wherein said Radio Frequency Identification element comprises at least one communication controller ( 21 ).
7. The battery of claim 6 , wherein said Radio Frequency Identification element comprises a plurality of communication controllers ( 21 ) in order to communicate over different frequencies and/or different communication protocols.
8. The battery of claim 6 , wherein said communication controller ( 21 ) comprises an interpreter, in order to execute received instructions in an object-oriented or procedural language.
9. The battery of claim 6 , wherein said communication controller ( 21 ) has a stand-by mode.
10. The battery of claim 6 , wherein said communication controller ( 21 ) can be roused from the stand-by mode through signals received over said radio interface ( 20 - 21 ).
11. The battery of claim 6 , wherein said communication controller ( 21 ) can be roused from the stand-by mode by the mobile telephone ( 3 ).
12. The battery of claim 1 , wherein it comprises a storage area for storing the user's identity.
13. The battery of claim 12 , wherein said identity comprises biometric parameters of the user.
14. The battery of claim 12 , wherein said identity comprises an electronic certificate of the user.
15. The battery of claim 14 , wherein it further comprises data processing means ( 21 ) for the signing of electronic communication.
16. The battery of claim 1 , wherein it comprises a storage area for storing monetary amounts transmitted over the contactless interface.
17. The battery of claim 1 , wherein it further comprises electric contacts for communication between said Radio Frequency Identification element ( 22 ) and said mobile radio telephone ( 3 ).
18. The battery of claim 1 , wherein it comprises a modulation element connected with said Radio Frequency Identification element for modulating the feeding voltage transmitted over said feeding contacts ( 22 ).
19. The battery of claim 1 , wherein it comprises an additional contactless interface for communication between said Radio Frequency Identification element and said mobile radio telephone.
20. The battery of claim 1 , wherein it comprises an adapter module for a chip-card.
21. The battery of claim 1 , wherein said radio interface operates according to the Bluetooth standard.
22. Set of different batteries ( 2 ) according to one of the preceding claims, the housing and the electric feeding contacts ( 22 ) of all batteries in the set being compatible with the same model of mobile telephone ( 3 ), wherein each battery ( 2 ) comprises a radio interface operating according to another protocol.
23. Mobile radio telephone ( 3 ) with the following components: an interchangeable battery ( 2 ), comprising battery cells in a housing, electronic data processing means as well as a radio interface ( 20 - 21 ) designed for bi-directional connections over electromagnetic waves, electric feeding contacts ( 22 - 31 ) for powering the mobile telephone ( 3 ) through said battery, an additional interface for communication between said mobile radio telephone and said electronic data processing means ( 21 ).
24. The mobile radio telephone of claim 23 , wherein it has a stand-by mode and wherein it can be roused from the stand-by mode through signals received over said radio interface ( 20 - 21 ).
25. Communication method between a mobile radio telephone ( 3 ) and an external device ( 1 ), wherein the communication takes place bi-directionally over a radio interface ( 20 , 21 ) in the battery ( 2 ) of said mobile telephone ( 3 ).
